Wherein, in order to prevent the heat dissipation effect near the liquid outlet from being relatively poor near the water inlet after the water temperature gradually rises, the liquid cooling flow channel 40 is composed of a first flow channel 41, a second flow channel 42 and a third flow channel 43 which are sequentially communicated, and the outlet of the first flow channel 41 and the outlet of the second flow channel 42 are arranged in a staggered manner, so as to achieve the effect of the cooling liquid flowing back in the accommodating cavity, thereby ensuring the temperature uniformity of the radiator structure 100. Specifically, the first baffle 31 and the second baffle 32 may be welded to the casing 10 by a brazing technique to ensure the stability of the connection between the first baffle 31 and the second baffle 32. The first flow channel 41, the second flow channel 42 and the third flow channel 43 may be disposed in an S-shape, so as to increase the flowing length of the cooling liquid in the accommodating cavity, thereby improving the heat dissipation efficiency, and meanwhile, the cooling liquid flows to a plurality of positions of the accommodating cavity along the first flow channel 41, the second flow channel 42 and the third flow channel 43, so that the cooling liquid at each position of the accommodating cavity flows stably and directionally, thereby improving the temperature uniformity of the heat sink structure 100. In addition, the cross-sectional area of the second flow channel 42 is larger than the cross-sectional area of the first flow channel 41 and the cross-sectional area of the third flow channel 43, and the second flow channel 42 covers the area where the heat dissipation fins 20 are located, that is, the flow velocity of the cooling liquid in the second flow channel 42 is relatively slow, so that the cooling liquid can fully contact the heat dissipation fins 20 when flowing to the second flow channel 42, and the flow velocity of the cooling liquid in the first flow channel 41 and the third flow channel 43 is relatively fast, so that heat can be rapidly taken away, which is beneficial to improving the heat dissipation efficiency, and further improving the heat dissipation effect of the heat sink structure 100.
Further, the housing 10 is defined to have a length direction, and the first baffle 31 extends along the length direction of the housing 10; the second baffle 32 comprises a fixed section 321 and a flow guide section 322, wherein the fixed section 321 is connected to the shell 10 and is arranged at an interval with the end of the first baffle 31; an outlet of the first flow channel 41 is formed between the fixed section 321 and the first baffle 31, an outlet of the second flow channel 42 is formed between an end of the flow guide section 322, which is away from the fixed section 321, and the housing 10, an extending direction of the flow guide section 322 is parallel to an extending direction of the first baffle 31, and the flow guide section 322 is connected with the fixed section 321 in a bending manner. Specifically, the fixing segment 321 and the guiding segment 311 may be an integral structure to ensure the overall structural strength of the second baffle 32. The extending direction of the first baffle 31 is the same as the length direction of the housing 10, and meanwhile, the first baffle 31 is connected to the housing 10 and arranged opposite to the liquid inlet 1121, so that the cooling liquid entering from the liquid inlet 1121 flows along the extending direction of the first baffle 31 to flow to the outlet of the first flow channel 41 and flow along the extending direction of the fixed section 321, and the flow guide section 322 and the fixed section 321 are bent and connected, that is, the joint of the flow guide section 322 and the fixed section 321 is arranged in an arc shape, so as to guide the cooling liquid, so that the cooling liquid flows along the extending direction of the flow guide section 322, flows out from the outlet of the second flow channel 42 to the third flow channel 43, and finally flows out from the liquid outlet 1122. Thus, the cooling liquid flows along the first flow channel 41, the second flow channel 42 and the third flow channel 43 directionally and rapidly, so as to further improve the heat dissipation capability and ensure the temperature uniformity of the heat sink structure 100.
Referring to fig. 6 and 7, in an embodiment of the present application, the partition assembly 30 further includes a third baffle 33, the third baffle 33 is connected to the housing 10 and located in the third flow channel 43, and the third baffle 33 is disposed opposite to an outlet of the second flow channel 42. In order to ensure that the cooling liquid flows along the extending direction of the third flow channel 43, the third baffle 33 is disposed to be connected to the housing 10 and to be disposed opposite to the outlet of the second flow channel 42, so that the cooling liquid is blocked by the third baffle 33 when flowing out from the outlet of the second flow channel 42, and the cooling liquid is guided to flow along the extending direction of the third flow channel 43, and is not flowed to other areas, so as to improve the heat dissipation efficiency. It should be noted that, in order to further improve the heat dissipation efficiency, the third flow channel 43 may cover the area where the heat dissipation fin 20 is located, so that the cooling liquid contacts the heat dissipation fin 20 when flowing to the third flow channel 43 to improve the heat dissipation capability.
Further, the housing 10 is defined to have a length direction, the length value of the third baffle 33 is L1, the length value of the housing 10 is L2, and L1 < L2. Specifically, in order to enable each surface of the heat sink structure 100 to have a good heat dissipation effect on the outside, the length value of the third baffle 33 is L1 and is smaller than the length value of the housing 10, which is L2, so as to prevent the third baffle 33 from completely blocking the inner surface of the housing 10 and causing the surface not to dissipate heat for other devices, and therefore, if L1 is less than L2, the third baffle 33 can ensure that the third baffle 33 has an effect of guiding the cooling liquid to flow along the extending direction of the third flow channel 43, and the heat dissipation capability of the heat sink structure 100 is ensured at the same time.

Wherein, the quantity of this base plate can be two and be the plane plate body, 11 both ends openings 111 of this frame main part, connect in frame main part 11 and respectively shroud two sealed openings 111 in order to form the holding chamber by two base plates 12 again, two base plates 12 accessible screws or buckle etc. can dismantle the mode of connection and be fixed in frame main part 11, so that installation in earlier stage and later stage maintenance change, simultaneously because radiating fin 20 connects in at least one base plate 12 department, and then also be convenient for maintain the change radiating fin 20. Secondly, the outer wall of the opening 111 of the frame body 11 is provided with a sealant, so that when the substrate 12 is connected to the frame body 11, the substrate 12 presses the sealant to ensure the sealing effect of the accommodating cavity, thereby further ensuring the directional flow of the cooling liquid in the accommodating cavity. In addition, the separation assembly 30 can be directly connected to the frame body 11 and located in the accommodating space, and in order to improve the installation efficiency, a yielding port is formed in the bottom of the frame body 11, so that the separation assembly 30 can be installed and fixed in the accommodating space of the frame body 11 through the yielding port, and the frame body 11 further comprises a bottom plate 112 for blocking and covering the yielding port, so as to ensure the sealing performance of the accommodating cavity.
Further, the material of the substrate 12 is different from the material of the frame body 11, and the heat dissipation coefficient of the material of the substrate 12 is greater than the heat dissipation coefficient of the material of the frame body 11; specifically, in order to avoid the over-weight of the heat sink structure 100 and ensure the heat dissipation efficiency of the heat sink structure 100, the material of the substrate 12 is different from the material of the frame body 11, and since the heat dissipation fins 20 are connected to the two substrates 12, that is, the substrate 12 is used as an area with a large heat dissipation effect, in order to improve the heat dissipation efficiency of the two substrates 12, the material of the two substrates 12 may be a material with a high heat dissipation coefficient, such as copper, and for an area with a weak heat dissipation effect, the structures, such as the frame body 11 and the water nozzle 13, may be made of other alloy materials, such as plastic and stainless steel, and further, the cost and the weight of the heat sink structure 100 may be reduced. Therefore, the use of the dissimilar materials can reduce the weight and the cost of the whole radiator while keeping the heat dissipation performance of the original radiator.
